Manufacturing Dowel Screws with Dual-Ended Threads Using CNC G76 Thread Cycle
Submit by: Vikram
Summary
Screw with threads on both ends (dowel screws) can be easily manufactured on cnc lathe using G76 threading cycle.
Following program cuts the same screw with RH (right hand thread) on one end and LH (left hand thread) on the other end using G76 threading cycle.
